[[File:Bakuman-349931.jpg|thumb|left|162px|Aoki's more aloof and tight-lipped appearance when she is first introduced.]]Aoki has short
brownish blonde hair and honey-colored eyes. She can be distinctively be seen with glasses when she reads and is easily identified by the iconic beauty mark under her left eye and her soft, fashionable, and strongly feminine taste in clothing which usually consists of various skirts and cardigans/sweaters. Her appearance in the manga has slightly changed with her character development to a more traditionally motherly role in a manga (enlarged breasts and kinder, softer eyes). [[File:Bakuman-2186055.jpg|thumb|104px|Aoki in a more recent chapter]]
When she is first introduced, Aoki is presented as extremely haughty, judgmental, and dogmatic, similar to the later fully introduced [[Aiko Iwase]], but as the story progresses, she undergoes enough character development to overcome her initial attitude (revealed to be caused by a distrust of men) and show a more tender, kinder, and more agreeable character.
It isn't revealed until she begins talking to [[Akito Takagi]] that, in the beginning, she believed that men were unreliable and that, despite her previously pompous pride towards her romances, she had never dated. However, as the storyline progresses, Aoki develops a crush on Takagi and starts to trust men more. This is made most prominent when she swallows her pride to ask for help from [[Shinta Fukuda]] in order to properly draw
panchira. She has also developed a romantic relationship with [[Kazuya Hiramaru]] and became engaged to him.
<span style="font-style: normal; ">Aoki is also shown as being very innocent especially on matters of love. This is due to her inexperience with men. The first man that she could really trust was Takagi when they agreed to help each other understand the opposite sex for their respective mangas. It is also due to this innocence that she did not realize the awkwardness of admitting to having started to like Takagi after encouraging Takagi and [[Kaya Miyoshi]] on their planned marriage. In contrast, she is able to quickly figure out Iwase's feelings for Takagi after hearing them converse. </span>
In a blatant shonen moment, Aoki walks downstairs to Nakai and allows the obese man to hit her and release any pent-up anger towards her. She finds that Nakai found himself unable to hit her, him knowing that he is the one at fault. A while after, Hiramaru, realizing that Nakai and him both "suffer from their affections towards Aoki", asks Nakai to be his assistant.
Aoki is later discussed again as another part of [[Yoshida]]'s plans to improve Hiramaru's manga and Nakai's lifestyle by encouraging them to work hard together with an idea: He says that the possibility of Aoki marrying Hiramaru would cause a physically improved Nakai(Another of Yoshida's plan) to meet Aoki's older sister at the rhetorical wedding and that a relationship could spark between the two. It isn't clear if Yoshida made up the idea that Aoki has
an older sister , but it's implied that she isn't real.

Hideout Door ''is about a boy who opens a door to the fairy world. He is then given a choice between choosing to gain the soul of a fairy and befriend them or die. As her art wasn't suited for a shonen audience at the time, she would only work on the story.
''A Time of
Green Leaves'' (''A Time of Blue Leaves'' in anime) was an ecchi manga in which she drew numerous panty shots learned from [[Fukuda]], demonstrating a shift of her manga into the shonen demographic. The manga was later canceled alongside Hiramaru's ''Otters 11'', setting the Love Fiesta in motion.
In the Love Fiesta, she took first place with her one shot
''What God Gave Me...''; which expands to become her next series. This series is canceled not long after, prompting Hiramaru to take her to the amusement park for his proposal.
